ST. PETERSBURG, Fla. – The Detroit Tigers placed shortstop Jose Iglesias on the seven-day concussion disabled list Friday morning (retroactive to Thursday) and called up top prospect reliever Joe Jimenez from Triple-A Toledo.

The Free Press reported the expected move Thursday evening.

In another transaction after Thursday's 8-1 loss to the Tampa Bay Rays, the Tigers called up left-handed reliever Blaine Hardy from Toledo and sent down right-handed reliever Warwick Saupold, who did his job in eating up long-relief innings in a sweep by the Rays.

Jimenez, who was called up April 11 and then optioned back down two days later after pitching one scoreless inning, will re-join the Tigers sooner than the required 10-day minimum because of the DL situation with Iglesias.

Tigers manager Brad Ausmus said Iglesias’ roster standing will be determined in the “near future.”

Jimenez, 22, has been dominant this season with the Mud Hens. In five appearances, he has allowed no runs on three hits, with 10 strikeouts and two walks.

Jimenez made his major league debut against the Minnesota Twins on April 13. With the Tigers’ bullpen remaining a work in progress, it was only a matter of time before they called on Jimenez again.

As for Saupold, 27, he threw 4 1/3 innings against the Rays, allowing three runs on three hits – all solo home runs in mop-up duty during this afternoon’s loss.

In the performance, he became the first Tigers reliever to allow three home runs in a game since Joba Chamberlain on July 1, 2015, against the Pirates, though those home runs did not diminish his standing: The Tigers look at him as a starting rotation insurance piece down the road.

“I thought he pitched OK overall,” Ausmus said. “Once in a while, that happens. He pitched well, we’d just rather have him down there pitching every fifth day in case there’s a need up here in the starting rotation.”

Hardy, 30, gives the Tigers another lefty relief option against the Twins, who carry multiple lefty hitters. He threw a scoreless inning April 6 against the Chicago White Sox and has allowed one run on four hits in 7 1/3 innings with the Mud Hens.

With Kyle Ryan struggling, it’s an opportunity for Hardy to establish footing on the major league roster.
